3D visualization of a reactive diapiric wall
with a complex pattern of en-echelon faults
forming a crestal graben on the seafloor above it.

3D visualization of a reactive diapiric wall
with young active faults bounding the crestal graben
while older (inactive) buried faults are seen on on the flanks.
These were active as crestal-graben faults in the past.
Crestal-graben faulting is a key component of reactive diapir growth.
